High-resolution Continuous Liquid Interface Printing (CLIP) technology is a promising and powerful additive manufacturing techniquefor delivering high-resolution micro-architectures with phenomenal print quality suitable for a wide range of applications, including bio-oriented applications in drug delivery, optics, sensors fabrication, and microelectronics backend packaging, due to its cost-effectiveness, high-accuracy, high-speed and wide selection of materials that can be used. A new high-resolution3D printer using the Continuous Liquid Interface Printing (CLIP) technologyis recently developed. Using our customized optical system, home-built software, and hardware interface to control the translational stage and the projection of digital micromirror device, we can now print 3D microstructures with a diversity of materials, at lateral resolution of 30 μm, 3.7 μm, 1.5μm, axial resolution at &lt;1um,and at print speed 100 times faster than conventional stereolithography. By incorporating photopolymerization kinetics modeling, optical system simulations, and fluid dynamics simulation of different polymeric material, we are inparallel developing a digital twinof the 3D CLIP printer that allows us to better understandour 3D printing process, seek solution in improving the resolution beyond current processes, and finally enable “smart-print” that dynamically tailor to different print materials and optimizethe print parameters to minimize the error between final print parts and design. Taken together, this works builds upon the fundamental understanding of polymer physics, photo-polymerization kinetics and optics and combining them through hardware implementation, software control and physical chemistry modeling, that can significantly advance the current landscape of additiveprinting technology that will benefit multidisciplinary research fields.
